'Discard this line' and 'Stage this line' options are too close in the right-click menu

These are diametrically opposed actions, but yet so close to each other.

I've accidently discarded a block of code instead of staging and it was immediately and completely and totally gone, much to my chagrin.

I'd suggest some more vertical space between them - perhaps a divider line?

Also, Stage (positive action) should be first, not Discard (negative action) - but probably a bad idea to change now since everyone is familiar with the current order.
